Estradot

​​Estradot is a type of Hormone Replacement Therapy or HRT.  ​When you go through the menopause your ovaries stop producing eggs and this causes a drop in the levels of the hormone oestrogen in your body.  ​Estradot contains the active ingredient estradiol hemihydrate, a substitute for oestrogen.  ​Estradot comes in the form of a transdermal patch – this means patch that you apply to the body below the waistline which gradually releases the hormone into your body.​ 

​​​The menopause is just another stage in life for many women and despite the side effects is often a welcome one as it means the end of periods and potential pregnancy. However, it isn’t something that happens overnight and for some women, it causes no end of problems with symptoms like hot flushes, mood swings, night sweats, low libido and more which can seriously harm their ability to lead a normal life. Many women who are suffering turn to Hormone Replacement Therapies to help them. There are a wide variety available in several different forms, from pills to patches to topical creams, and finding the right one can be a process of trial and error. On the plus side once you’ve found it you should hopefully feel able to cope with whatever life throws at you.​​ 

What is ​Estradot​? 

​​Estradot is a type of Hormone Replacement Therapy or HRT. 

​When you go through the menopause your ovaries stop producing eggs and this causes a drop in the levels of the hormone oestrogen in your body. 

​Estradot contains the active ingredient estradiol hemihydrate, a substitute for oestrogen. 

​Estradot comes in the form of a transdermal patch – this means patch that you apply to the body below the waistline which gradually releases the hormone into your body.​ 

When is ​​​Estradot​​​ used? 

​​Estradot is used by women who are postmenopausal, so in the later stages of menopause. You must have had at least 12 months since your last period. 

​It is used to relieve the symptoms of menopause such as: 

  • ​hot flushes 
  • ​mood swings 
  • ​low libido 
  • ​night sweats 
  • ​headaches 
  • ​palpitations 
  • ​joint pain or stiffness 
  • ​vaginal dryness 
  • ​difficult sleeping 
  • ​reduced muscle mass 

​Estradot is also used to prevent the onset of osteoporosis in women who are more prone to fractures if other medicines are deemed unsuitable.​ 

How do you use ​​​Estradot​​​? 

​​Estradot comes as a transdermal patch, you change the patch twice a week.  

​To apply the patch: 

  • ​Decide where you are going to place the patch, on the torso, below the waistline where it is unlikely to be rubbed by clothing etc. 
  • ​Make sure your skin in that area is clean dry and cool; 
  • ​Remove the patch from its individual protective pouch; 
  • ​Peel off one side of the protective backing, avoid touching the sticky side with your fingers; 
  • ​Hold the side with the backing and press the sticky side firmly onto your skin, in the desired area; 
  • ​Fold back the remainder of the patch and pull off the other piece of protective backing; 
  • ​Press the patch firmly onto your skin for 10 seconds; 
  • ​Check that it is firmly stuck around the edges; 
  • ​You can now carry on as normal, shower, swim, run etc. and the patch should stay firmly in place; 
  • ​When is it time to remove the patch and change it, fold it in half with the sticky sides together so that none of the remaining medicine escapes, and dispose of it in your normal rubbish; 
  • ​Apply the next patch in a different location to minimise the risk of skin irritation.​ 

What dosages are there? 

​​As with all medicines, you should follow the instructions of your doctor or pharmacist when it comes to the right dose for you. 

​Estradot patches come in several different doses: 

  • ​25 micrograms; 
  • ​37.5 micrograms; 
  • ​50 micrograms; 
  • ​75 micrograms; 
  • ​100 micrograms. 

​The numbers refer to the amount of estradiol that is released into your body. Your doctor will decide which dose you will start with. The guidelines for all HRTs is to take the lowest possible dose for the shortest possible time in order to relieve your symptoms. 

​No matter what dose patch you are using the cycle is the same. 

  • ​Change your patch twice weekly (every 3-4 days); 
  • ​Try to change them on the same two days of the week, it will be easier to remember if you follow a regular schedule; 
  • ​Wear the patch continuously until it is time to change it; 
  • ​Change the location of the patch each time you change it so your skin does not become irritated; 
  • ​If a patch comes off before it should, simply replace it with a new patch and then change that one on your usual day; 
  • ​If you still have a uterus you will also be prescribed a hormone called progesterone to take while using Estradot patches.
